[8] Review request for 7161568 [macosx] api/javax_swing/JTabbedPane/index2.html#varios fails

[Alexander Scherbatiy]

Hello,
Could you review the fix:
  bug: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7161568
  webrev: http://cr.openjdk.java.net/~alexsch/7161568/webrev.00

  The JTabbedPane.getBoundsAt(int index) now returns null if the tab 
index is not currently visible in the UI.
  This is done according to the specification: 
http://docs.oracle.com/javase/6/docs/api/javax/swing/JTabbedPane.html#getBoundsAt%28int%29

  The issue is covered by JCK tests so a new regression test is not added.

Thanks,
Alexandr.
